c Test Lead Connections. See GENERAL INST­
RUCTIONS^.
The test leads connected to the meter are applied
across the voltage to be measured, the red lead to
plus and the black lead to minus potential of the
load.
In most cases, minus side is earthed or
connected to the chassis. When measuring, the
black lead may be fixed to the chassis, and voltage
is checked by applying the red lead to the check
point. (Fig. 1-3 & -4)
W ith pnp transistor circuits, the plus potential of
the battery is earthed, and the connections of the test
leads are reversed.
W rong connections deflect the pointer to the left.
Just reverse the connections if this occurs.
d Scale Reading. Use the black scale just below the
mirror marked
DCV»mA
for all DC voltage measure­
ments. (Fig. 1-5)
